Vertical Antennas-Ground Radials



If you can't see the video, please insert this title URL into your browser search box:


One of the major problems with vertical and random length wire antennas is the installation of an effective ground radial or counterpoise system.  Without a good ground radial system, the performance of your 1/4 wavelength vertical or long wire antenna will suffer.

In this video from Callum McCormick (M0MCX), we see one way to design, install, and test a ground radial system for HF vertical antennas.

Here are some of Callum's comments:

Ground Radials are a thing of "Mystique". I use the formula of using 4-wavelengths of wire in total, cut into random lengths to suit.All my radials are LESS than 1/8th of a wavelength. For 80m, my radials are around 2.4% of the wavelength. My experience and demonstration in a real-world solution will assist our thinking.
